Oibalus was the son of either Cynortas or Argalus. He was the second husband of Princess Gorgophone and thus son-in-law of the hero Perseus. With her or by the NaiadBateia, Oibalos fathered Tyndareus, Icarius and Hippocoon, as well as a daughter, Arene, who married her half-brother Aphareus. The nymph Pirene and Hyacinth were also called the daughter and son of Oebalius respectively. His grandchildren, the Dioscuri, were usually referred as Oibalids or Oebalidae.
Oebalus was often confused with Gorgophone's first husband, Perieres, son of Aeolus. They were separate people, usually unrelated though Oebalus was sometimes said to be Perieres's son.
↑Ovid, Heroides 16.127 ff; not directly named as the son of Oebalus but Helen, the reputed daughter of Tyndareus was called "... a nymph of Oebalus' line ..." which means she was a descendant of the latter through his son Tyndareus.
↑Valerius Flaccus, 1.420 ff; mentioned that Pollux was called the grandson of Oebalus, the father of their father Tyndareus.
